I am going to go single and Chuck has recommended this kit to me did search and found very little. I would be interested in some input on my selection. Thanks

 

This is to mounted on a HKS stainless steel manifold with a Tial 46 mm wastegate

 

my friend had this kit from Chuck and he is really like it.he had low compression stock motor but his car still make 330 whp at 13 psi.the turbo spool at 3200 rpm.if you are looking for 400 whp at 15 psi and still get quick spool then you should get the to4r ,it is about $400-500 different.i got the to4r and my motor got only 90psi(6 bar) and i made 375whp at 14.2 psi

 

Thanks, that sounds like what I want. A daily driver in fair weather conditions that I can play with at the track. I wonder if that HKS can have something larger added at a later date if desired?
